Question

Four students were loading boxes of food collected during a food drive. The force that each student exerted while lifting and the distance each box was lifted are listed in the table.

A 3-column table with 4 rows. The first column labeled student has entries Chet, Mika, Sara, Bill. The second column labeled Force (Newtons) has entries 50, 40, 30, 60. The third column labeled Distance (meters) has entries 1.0, 2.0, 1.5, 0.5.

Which lists the students in order from the greatest amount of work done to the least? (Work: W = Fd)

Bill, Sara, Chet, Mika
Mika, Chet, Sara, Bill
Bill, Chet, Mika, Sara
Mika, Sara, Chet, Bill

Answer 1

Compute W = Fd for each:
- Chet: 50 N × 1.0 m = 50 J
- Mika: 40 N × 2.0 m = 80 J
- Sara: 30 N × 1.5 m = 45 J
- Bill: 60 N × 0.5 m = 30 J

Order greatest to least: Mika, Chet, Sara, Bill.
